Inventor: RIETSCHEL WOLFGANG DIPL ING
IPC: C12M1/12
Filed: 1987-06-16
Abstract: An immersion tube dipping into a fluid is connected via a valve and via a 3/2-valve to a condensate line and to a working line. In the sterilization position, vapor flows through the valve and through the 3/2-way valve and the valve is in a position which is open to the head space of the vessel and to the tube. As a result, all of the inner space of the vessel is exposed to the same pressure. In the operating position, the valve connects the duct only to the interior of the immersion tube, while the connection to the head space is blocked. All components connected to the line are sterilized by vapor.

Patent DE-3728381-A1 (DE)
Inventor: MAIER GERHARD
IPC: H04N5/76
Filed: 1987-08-26
Abstract: When connecting an antenna (2) to two loads, for example to a video recorder (1) and a television receiver (9), the video recorder signal is converted into the frequency of a television channel via a modulator (12) for replay purposes and connected to the antenna input (10) of the television receiver (9). This creates disturbances due to crosstalk with other television channels which appears as interference stripes on the screen. A remedy is associated with costs due to a separate antenna switch. 
<??>Between the antenna signal preamplifier (4) and the input (10) of the television receiver (9) connected to the modulator (12), an attenuating section (14) (frequency trap) is connected, the trap frequency of which is identical with the modulator frequency and tracks the modulator frequency tuning.

Patent DE-3737667-A1 (DE)
Title: Carburettor for internal combustion engines
Inventor: GERHARDY REINHARD DIPL ING
IPC: F02M17/04
Filed: 1987-11-06
Abstract: The inlet valve of the carburettor is opened by the pressure of the fuel pump which prevails when the engine is started. As soon as the engine starts up, the supply of pressure is interrupted by a change-over valve so that the inlet valve closes. There is the risk of the inlet valve being contaminated by combustion residues and no longer closing satisfactorily. The intention is therefore to close the inlet valve reliably after the engine starts up. An actuator lever which has the inlet valve is forcibly moved by an actuation element into a position in which the inlet valve assumes its open position. The pressure in the crank housing is no longer used to open the inlet valve so that the inlet valve can be opened even before the engine starts. The carburettor is used in internal combustion engines, in particular for portable miniature engines.

Title: Steel heating-boiler
Inventor: HENCHE WOLFGANG
IPC: F28D9/00
Filed: 1987-12-07
Abstract: In a steel heating-boiler with a downdraught burner (5) arranged in a combustion chamber (6), there is arranged below the combustion-chamber bottom (10) a heat exchanger (17) which is passed through by approximately vertical waste-gas ducts (13 or 48) and approximately horizontal water ducts (21 or 40) which run one above another in different planes, the flow direction of the water in the water ducts (21 or 40) changing by plane. In order to develop such a steel heating-boiler (1) designed as a cross counterflow device into a condensation heating boiler with great efficiency, the heat exchanger (17) is in the region of the combustion chamber (6) designed as a pure counterflow heat exchanger, the inlet (25) of which is arranged at the bottom in the burner axis (56) and the outlet (9) of which is arranged peripherally. The waste-gas path of the heat exchanger (17) can be formed by square tubes (13) welded to one another in regions and divided according to height by plates (20) which form the water ducts (21) running one above another. The heat exchanger (17) can, however, also be composed of stamped or edged metal sheets (42, 52, 58, 59) which delimit water ducts (40) and waste-gas ducts (48). <IMAGE>

Title: Method and device for the regeneration of soot filters
Inventor: BRESSLER HARALD DIPL ING
IPC: F02B3/06
Filed: 1988-02-03
Abstract: During the regeneration of a soot filter (4) for diesel engines the exhaust gas mass flow flowing through the soot filter (4) is greatly reduced by means of an exhaust flap (6) and the excess portion of the exhaust gas is diverted into a bypass (7). Due to the great reduction of the exhaust gas mass flow, the electrical heating (5) and the ceramic body (4) and the soot layers are only slightly cooled so that very little additional heat energy has to be fed in in order to reach the ignition temperature, which allows the heating coil (5) to be fed from the vehicle battery. Due to reduction of the oxygen mass flow, the layers of soot in the ceramic body (4) are burnt off at reduced speed and at relatively low temperatures, so that a long material service life is achieved owing to the low thermal stresses. <IMAGE>

Title: Concrete enclosing block
Inventor: ROTH REINER DIPL ING
IPC: E04C1/39
Filed: 1988-03-09
Abstract: The invention relates to a concrete enclosing block for the design of gardens, parks and landscapes and having the same wall thickness, the wall surrounding an air space of the same height, and having insertable base panels for the closure of openings. The essence of the invention consists in the fact that, in the outline of an imaginary square, in each case two adjacent sides are curved outwards and the two other sides are curved inwards, not over their entire length, but centrally. Two adjacent sides may also be shifted away from the square, parallel to the side of the square in each case. The essential advantages consist in the fact that a single concrete encircling block can be laid in formation and it offers the possibility of erecting closed walls, in the case of which planting levels, which can better absorb rainwater, can be created at any location.

Title: Anti-skid device for rubber-elastic vehicle tyres
Inventor: PIEKUTOWSKI GREGOR
IPC: B60C27/16
Filed: 1988-04-02
Abstract: Four tread strips (1), made of rubber or a rubber-like resilient material are spread out in front of the wheels of the passenger car illustrated in the drawing, in which material pin-like projections (3) protrude from the inside of the said strips (1), which pin-like projections (3) engage in the covers (5) of the tyres under the weight of the vehicle as the vehicle tyres (2) roll onto the tread strips and the said pin-like projections (3) are anchored or clamped tight there to such a degree that the drive traction can be transmitted from the covers of the tyres to the tread strips. On the outer face, the tread strips can be provided with a suitable profile in order to permit the vehicle to operate in winter, or under M + S conditions. In principle, however, the tread strips can be released from the covers of the tyres again, for example at the end of the winter season in order to be able to fit on new tread strips or tread strips with a different profile. The costs of such tread strips and therefore the costs of changing a profile are as a result much smaller than when changing a tyre. <IMAGE>

Title: Projectile having unfoldable wings
IPC: F42B10/14
Filed: 1988-11-10
Abstract: A projectile (84) is described which has unfoldable wings (12) which have at least two wing elements (14, 16) which can be displaced by means of a drive device (48) between a folded-up first position in which they are accommodated in a space-saving manner in the projectile fuselage (10) and a second position where they are folded apart from one another, point away from the projectile fuselage (10) and form the wing profile. In order to ensure a continuously smooth profile surface of the wing profile when the wing (12) is in the second position, all the wing elements carry out a fan-like rotary movement in the same rotation direction about mutually parallel rotation axes (18, 20) while they are folding out from one another. At the same time, at least some of the wing elements (14, 16) carry out a lateral displacement movement in a direction parallel to the associated rotation axis (18, 20), by means of an associated second drive device (76), on reaching or shortly before reaching the folded-out rotation-limit position, until the wing elements (14, 16) are aligned with one another in the profile longitudinal direction of the wing (12). <IMAGE>

Title: Anti-skid chain for tyres
Inventor: MUELLER ANTON DIPL ING
IPC: B60C27/12
Filed: 1988-12-02
Abstract: Anti-skid chains for tyres comprise a retaining and tensioning device composed of a plurality of bows which are fastened to rubber belts and are fitted with the latter into the wheel rim. A disadvantage here is that the retaining and tensioning device protrudes far beyond the outside of the tyre and that its fitting is complex. In order to be able to arrange the retaining and tensioning device tightly against the tyre side wall, it is formed by at least one tensioning part which lies against the inside of the tyre and exerts a tensile force onto the tread part, the tensile force being directed towards the inside of the tyre. This retaining and tensioning device lies in a protected and space-saving manner on the inside of the tyre. The tensioning part also exerts a pretensioning force onto the tread part so that the tyre chain guarantees very quiet running. Due to the pretensioning force which the tensioning part exerts on the tread part, the anti-skid chain for tyres can easily be fitted in the exact position. The anti-skid chain for tyres is particularly suitable for tyres of passenger cars.

Title: Electrical switching device having an electromagnetic switch drive
Inventor: GIEGOLD PETER
IPC: H01H9/02
Filed: 1988-12-14
Abstract: An electrical switching device, especially an electrical contactor, which is accommodated in a housing (which can be closed by means of a covering cap on the front and can then be security sealed) and is equipped with an electromagnetic switch drive has cable connection points both for the mains supply cables and load cables to be connected and for the control cables leading to the electromagnetic switch drive. The fastening means (which are arranged at the cable connection points) for the supplied ends of said cables can be operated from the front of the switching device when the covering cap is removed and are completely covered when the covering cap is installed. In order to prevent manipulations in the case of those switching devices which may be connected only at specific times of the day and/or night or in specific mains constellations (low-load times), it is proposed to provide the covering cap (12) with laterally projecting extensions (18) which additionally cover at least the two cable ends (which can be inserted into the housing (11) and are to be supplied) of the control cables for the electromagnetic drive, in such a manner that making contact with live parts of the associated cable connection points or the stripped ends of the control cables when the covering cap is installed on the housing is largely prevented. <IMAGE>

Title: System for generating an STM-1 signal (Synchronous Transport Module) from a 140 Mbit/s signal
Inventor: HENZE MICHAEL
IPC: H04J3/07
Filed: 1989-03-10
Abstract: System for generating an STM-1 signal from a 140 Mbit/s signal. The new synchronous digital hierarchy recommended by the CCITT defines multiplex signals with bit rates of 150-520 kbit/s and with multiplexing. The processing speeds required therewith can ultimately be implemented in serial operating mode only through leaps in technology (transition to ECL or GaAs technology) and, associated therewith, at substantial outlay and cost. Without substantial additional cost, the invention provides the prerequisites for the circuit arrangement to be designed completely in parallel to generate the elementary multiplex signal of the new synchronous hierarchy, the STM-1 signal, from a signal of an asynchronous standard. For this purpose, means 3, 4, 7 have been developed for synchronisation-dependent control of the clock rate divider 2 of the input-side serial-parallel converter 1 and means 10 for synchronisation-dependent control of a bytewise operating additive scrambler. The controllable clock rate divider 2 shortens, in corresponding pulses, the length of the byte clock which is provided in the virtual container for the fixed padding bit and for the padding bit for adapting the frequency of the system input and system output signal, so that bitwise padding is possible in the parallel buffer memory 3; the scrambler is controlled via AND gates 10 depending on and guaranteeing the frame alignment of the STM-1 signal ...
